Affect analysis of flood scouring of spillway on stability of Maya high slope;

Firstly,the washout formed by flood discharging is simulated by the excavation mode,and the effect of the washout for stress status,deformation status and stability of the two slopes is studied.

Formation mechanism of hyper-concentrated sediment flow caused by scouring of reservoir emptying;

Running the procedure,we could get adjustment of the survey of traverse conveniently;then we could also get axes and axes parallel lines in the left and right bank s tunnels for flood releasing and scouring sand.
